I think you missed the point of my issue. I know it was an OutOfMemoryException. What I was trying to explain is that my system has plenty of memory available: if you look at the results of `free` I posted, there are about 15GB of memory available. This happens often -- a system restart every time, especially when there are 15GB of memory available, is not an acceptable solution.

Can you give these troubleshooting steps a try to see if they help:

1. In case you're using an antivirus or firewall software, ensure Chrome is trusted or permitted by these programs. You can also try temporarily disabling your antivirus or firewall to check whether this determines the issue.
2. Uninstall and reinstall Chrome again.
3. Clear all Cache and Cookies.
4. Your profile account might have been corrupted. Try creating a new browser user profile and check if it helps.
5. Run a scan with chrome clean up tool. This will help in removing the malicious software from the computer which tends to conflict with Chrome.

6. Reset Chrome browser settings and check if it helps.

Thanks!

I have to wonder if you guys even read the description? You're sending debugging steps and tools for Windows, when this issue is for Linux.
